"China has noted the tough reactions made by the relevant countries over this event and is concerned over the development of the situation," Chinese foreign ministry spokesman Hong Lei told reporters.
"We hope relevant countries will keep calm and exercise restraint and avoid taking emotional actions that may rachet up the confrontation."
